增加Shadow map的精?度

akira32

我想要增加Shadow map的精?度(藉由定?在shader code的sampler的statement)
我???要如何定?"MinFilter" , "MagFilter" and "MipFilter"?(才??@得最佳的精?度)
使用"anisotropic filtering"??黾?hadow map的精?度??
如果要使用"anisotropic filtering"的?,在sampler中的statement要如何?⑹?

texture ShadowMap0;
sampler ShadowMapSamp0 = sampler_state
{
Texture = <ShadowMap0>;
MinFilter = LINEAR;
MagFilter = LINEAR;
MipFilter = NONE;

AddressU = Clamp;
AddressV = Clamp;
};

shadow map的精度不是由纹理采样来增加的．使用高分辨率的阴影可增加精度．

我是看adaptive shadow maps?篇paper,它提到?用anisotropic filtering可以提高精?度,我??@一?抱持著疑??.
